This is a great trigger. It is very easy to install, all you need to do is change over the spring and such from the stock trigger over to the Promark. The trigger is not made of cheap, flimsy plastic, and the guard isn't either. Also, theres no need to cut your grips to get the guard to fit like some other trigger kits. It immediately makes the pull lighter, right out of the package. If you are looking for a new trigger, or even a different double/blade trigger, spend a few extra $ and buy this. Its well worth it.

Conclusion:

Buy it. It preforms as well as it looks, and its steps ahead of other trigger setups.
